Hi,
Given a wsdl uri, how can I determine using Axis2 whether the services

if you`ll try for instance

I am sorry I didn't describe my question correctly. Apart from trying the
wsdl uri on the browser , Can I do this programmatically with some axis2 api
?

Thanks.

Sorry, i`m not familiar with axis2, i`m using axis 1.4.
But if axis2 has similiar architecture (activating web services trough 
servlet), then i think, that axis2 api has not functionality to do it.

But maybe you can try http client library in java.

2007-06-26 Thread Walker, Jeff 
This has been discussed before.
To my knowledge, there is no direct API in Axis 1.x or Axis2 that you
can call to do this. But, since it is a servlet, creating a GET request
and sending it and looking for the expected response will work. Then the
discussion moved onto whether this is acceptable in general, since http
may not always be the transport protocol. I also suggested writing a
very simple ping() method and put it into your web service interface,
but that's no different than calling any other method except it should
be quick and easy.

You could try this sort of thing as well:

...
public static boolean isWebServiceAvailable() {
boolean result = false;

MyWebService_ServiceLocator locator = new MyWebService_ServiceLocator();
  try {
java.lang.String url = locator.getMyWebServiceAddress();
java.net.URL netUrl = new java.net.URL(url);
java.net.URLConnection connection =
(java.net.HttpURLConnection)netUrl.openConnection();
connection.connect();
result = (connection.getContent() != null) ? true : false;
  }
  catch (java.io.IOException ioe) {
System.out.println(Caught an io exception:  + ioe.getMessage());
  }
  return result;
}

Actually axis2 has a 'Pingable' interface. An example of its use is here:

http://svn.apache.org/viewvc/webservices/axis2/trunk/java/modules/samples/ping/src/samples/ping/service/PingService.java?revision=511830view=markup
http://svn.apache.org/viewvc/webservices/axis2/trunk/java/modules/samples/ping/src/samples/ping/client/PingClient.java?revision=511830view=markup
